What you get
Most power banks stop at a phone and maybe a tablet. The Shargeek 300 targets laptops. Its 300W total output can run two 16-inch MacBook Pros at up to 140W each and charge a phone at the same time.
- Capacity: 24,000mAh, which Sharge says complies with airline rules
- Output: 300W total; two USB-C ports at up to 140W (PD 3.1), plus one USB-A port
- DC port: adjustable 5V–28V output (5.5 x 2.1mm) for Starlink, portable fridges, camera monitors, LED lights and soldering irons
- Recharge: 140W USB-C input, 0 to 100% in about 44 minutes
- Display: 1.9-inch screen that shows live power curves, individual cell voltages, cycle count, and estimated time remaining. You also set the DC voltage here.
- Build: CNC-machined aluminum unibody with full-tab cells (≤4 mΩ internal resistance), which Sharge says run up to 35% cooler
Who should buy it
Buy it if you carry a laptop and want one battery for the whole bag. The DC port also makes it useful for creators and campers who run 12V–24V gear. If you only charge a phone, it is overkill.
Cheaper option
If you want a pocket battery instead, UGREEN’s Nexode 45W 10,000mAh power bank with a built-in USB-C cable and smart display is $59.99 on Amazon (list $69.99).
